How to Install and Configure DHCP

This section contains the procedures you need to install and configure DHCP.

1. On a cluster member, become superuser or assume a role that provides solaris.cluster.modify RBAC authorization.

2. Create a cluster file system or highly available local file system for the DHCP files.

   Refer to Sun Cluster Software Installation Guide for Solaris OS for information about creating a cluster file system and to Sun Cluster Data Services Planning and Administration Guide for Solaris OS for information about creating a highly available local file system.

3. Mount the highly available local file system if used.

4. Configure DHCP.

   As root, execute /usr/sadm/admin/bin/dhcpmgr.

   # /usr/sadm/admin/bin/dhcpmgr

   • Choose Configure as DHCP Server.

   • Choose Text files or Binary files.

   • Enter a path for the DHCP network table.

   • Choose which name services to use to store host records.

   • Choose Length of Lease and whether clients can renew their leases.

   • If used, supply a DNS configuration for the DHCP client of this server.

   • Add which network and network mask should provide IP Addresses.

   • Choose LAN as Network Type.

   • If used, supply a NIS configuration for the DHCP clients of this server.

   • If used, supply a NIS+ configuration for the DHCP clients of this server.

   • Create your addresses and macros.

5. Ensure /etc/inet/dhcpsvc.conf is the same on all cluster nodes.

   This can be done by either.

   • Copying /etc/inet/dhcpsvc.conf to each cluster node.

   • Moving your edited /etc/inet/dhcpsvc.conf to a cluster file system and create a symbolic link from /etc/inet/dhcpsvc.conf to dhcpsvc.conf on the cluster file system.

6. Ensure DHCP is stopped on all nodes.

   # /usr/sadm/admin/bin/dhcpmgr

   1. If running Solaris 9

      # /etc/init.d/K21dhcp stop

   2. If running Solaris 10

      # svcadm disable dhcp-server
